Weird color shift on laser projection

Hi
I don't think this is strictly speaking a DCP-o-matic problem, but I'm not sure where else to ask.
I have created a DCP of our first feature film. J2C export from Resolve, DCP done in DOM.
When testing in the cinema we have found that the main screen shows a weird color shift - very visible in scenes with a lot of blue colors. It seems as though the colors are pushed toward purple. Most of the film looks fine though, but some scenes suffer a lot.
Now the weird thing is, that we also tested on a smaller screen in the same cineplex. On that it looks perfect - completely matching my calibrated monitor at home.
The main difference is that the big screen runs on a laser projector (Barco I think). They also have a different playback system. The tech guy at the cinema says this is due to some kind of perception issue with laser projectors, but I feel the tint is way too heavy to be explained by that.
Are we talking a calibration issue on the part of the cinema? Or is there something I'm not considering?
